Maybe actually DCHECK that size() == 1?

[jonross, 2016/12/06 21:09:32]

From discussions about a full standalone prefs service, there may end up being
more than one entry.

[sadrul, 2016/12/07 04:11:58]

Indeed. That's why I want this to be a DCHECK(), so that when that does happen,
we add the correct logic here to select the right entry, instead of always
picking the first one.

[jonross, 2016/12/07 15:46:39]

Oh... I follow now, sorry. Done.
